There is absolutely no information on this group and its personnel on the internet beyond the release of this lone UK single in February 1967.
The group played regularly at the Whisky A Go Go in Wardour Street in Soho, central London between 1967 and 1969. It also played at the Mistrale in Beckenham, south London a fair bit too among other venues.
There are rumours that Mr Mo’s Messengers evolved into Sketto Rich & Sonority (see entry on this site) but this seems very unlikely (as both bands were gigging simultaneously in the late 1960s).
However, there is a slight possibility that the musicians in the latter formation also used the name Mr Mo’s Messengers briefly, as both groups came from the southeast London/Kent borderlands.
If anyone can provide further information on the group’s history and its personnel, we’d be interested to hear from you (see comments section for what has been submitted so far).
